A patient support system having an environmentally controlled area over the patient including a frame with a patient support thereon and a moveable canopy thereover. The support is generally rectangular and is provided with a vertical fluid curtain at its perimeter on each of its four sides. The four vertical curtains are deflected inwardly by the canopy to provide the environmentally controlled area over the patient and with a fluid return to the perimeter to provide a closed fluid path. The air curtains can be heated and/or have water vapor added thereto. An infrared heater is provided in the canopy for a second source of heat. An integrated control system is also provided.
